DESCRIPTION
smcFanControl... Control the fans of every Intel Mac to make it run cooler.
smcFanControl lets the user set the minimum speed of the build in fans. So you can increase your minimum fan speed to make your Intel Mac run cooler. However in order not to damage your machines smcFanControl doesn't let you set a minimum speed to a value below Apple's defaults.
WHAT'S NEW
Version 2.2.2: - Offical support for every so far released Macbook, Macbook Pro, Macbook Air, mac mini included
- Fans of iMacs, MacPro’s are read out on first startup. For official support of iMac/MacPro in a future release please send me your ModelName and min/max speed for every fan.
- The fan to be displayed in the menubar can be chosen now
- All known memory leaks fixed
- Spanish localization included
REQUIREMENTS
Intel Mac with Mac OS X 10.4 or later.

DR. GIRLFRIEND Ordinarily, smcFanControl is a very good app, but I'm having an issue in Snow Leopard that I'd like to make others aware of: SMCFC randomly shuts down without warning. This has happened numerous times after a reboot or after waking the computer from Sleep. It's happened on a clean install of Snow Leopard and I didn't notice until the temps were running quite high on (Original 2006 MacPro) and my fans kicked up a few decibels on their own, alerting me to the problem. Please note: I don't this this is SMCFC's fault; I think this is a Snow Leopard bug as I've noticed other instances of the O/S not remembering various preferences (keyboard modifier keys, Wacom tablet settings, etc) or apps that I've set to open automatically at login. Hopefully Apple will have a fix soon. In the meantime, keep an eye on your system because SMCFC isn't 100% stable on Snow Leopard yet.

JONATHAN ROWSON I have found this to be extremely helpful. One tip I can offer is to realization that the fan circulates air taken in from the keyboard. This is crucial if you have a keyboard protector like an iSkin (like I have) that will affect circulation. One non scientific test had my MBP running at 160 deg. F, which dropped to 135 with removal of the skin allowing circulation when the fan was trying to drop the temp.

STILL_SPARKLING This app is fantastic. A couple of years ago I had a bad experience with an Apple EFI Firmware Update which, after install, made the fans on my MacPro sound like a jet turbine; the sound was ceaseless and unbearable. The Apple tech who worked on my MacPro agreed that the fans were running too high. Luckily, I was still under AppleCare because he ended up replacing the entire logicboard. Ever since then, I've used smcFanControl with great success and never touched another Apple firmware update that "adjusts fan behavior". smcFanControl lets me keep my default fan settings nice and low -- I like a quiet system -- for most tasks, but also allows me to crank the fans up, individually or globally, when needed. It also allows you to easily create and save different profiles; with these profiles you can switch, in one click, to higher or lower fan speeds when you need to adjust the cooling. SMCFanControl is an outstanding addition to my arsenal of essential Mac apps. It's cool that it's free, but if you depend on it every day like I do, you should donate to support its development (especially with Snow Leopard right around the corner).

PFROCKER For a while I had SMC fancontrol and it was working great, but then I uninstalled it and wanted to try fancontrol, which sucked. So I uninstalled fan control (both the preference and the daemon) and re-installed smc. But now when I click on the app, in the menu bar it says "smc..." for a while and then goes away and nothing happens. Please someone tell me what I'm doing wrong? I need to cool my laptop.

YABA-DABA-DO ;-) This tip/hint is for the person that says smcFanControl resolved his/her noisy machine. As the story goes about 9 months ago my 20"imac was making and awful noise and i started asking around and figured out it was my right side case fan. My machine was still under factory warrantee so i took it in and sure enough thats what it was. The technician told me the bearing mechanism failed, so by turning up the rpm has some what temporality masked what is a serious problem with your machine!..;-)

AVIDMCUSER Works great. Just wondering if its normal for the fans to take a long time to spin down after changing the settings back to default values. It is taking approximately 5 - 7 minutes for the fans to reach default speeds from maximum. Is this a symptom of inertia or a hardware pre-programmed decline for a smoother temperature transition? Any ideas would be appreciated. -Aluminum iMac 24" / 2.8ghz C2D / 2gb / 300gb

SCIFI It seems the author has fixed the problems mentioned below with v2.2.2 available at his website. Hoping he will come back here to fix the links as well. ;)

NOTAFOOL Sorry, but the newer version is just as bad the previous one. It simply does NOT - repeat NOT - launch on my computer, (Details of my computer and OS are in my first posting). This is extremely disappointing. Quite frankly, I no longer have ANY confidence in this application at all and shall NOT be trying it again. It appears to have been quite inadequately tested on the VERY machines that it purports to have been written for, and is bug-ridden. It has been released far too prematurely and simply does NOT work. BEWARE !!

NOTAFOOL This latest version - purporting to have been released today (21 April 2009) - is no better than any of the previous version I have tried. It still totally refuses to launch or do anything whatsoever. It remains a total LEMON as far as I am concerned. I have had quite a bit of correspondence with the Developer and have sent him crash reports, logs etc. So far he has no idea why it doesn't work for me. But it certainly doesn't. And check out his website. Many, many people are having all sorts of problems with it. It is simply NO good.

Drag smcFanControl to the Dock manually. Then when you have it on your Dock, right-click (or control-click) the icon and select "Open At Login" and then restart the computer. It wasn't launching at startup for me either until I did this manually. See if it works for you.

NOTAFOOL I did exactly as you recommended STOOPID MONK3Y. Absolutely NO difference whatsoever. The dopey application STILL totally refuses to launch. NOTHIng. ABSOLUTELY NOTHING. Not even the remotest hint that it is launching. I have given up on this dopey application now. It is a total LEMON as far as I am concerned. I have had correspondence with the Developer, who appears to have absolutely no idea why it will not launch even though I have sent him crash reports etc. I have now trashed this irritating application and intend having NOTHING to do with it. It appears to have more bugs in it than an entomologist's laboratory.

ST00P!D M0NK3Y Dude, it's working perfectly for me and thousands of others. Don't know what the issue is and I wish I could tell you, but there must be something funky in your system from preventing the launch of this app. If even the developer can't help you, I don't think anyone else can. Maybe wait for a newer release or just ditch the program altogether. The updates seem to be far and few between though so you might be waiting a while.

M. LUTHER Works fine for me. And if a stoopid monkey can get it working, then its gotta be something funky with your system.

NOTAFOOL Every other application on my computer works absolutely fine. I have run both Disk Warrior and Drive Genius over it and both give it a 100% clean bill of health. If my computer is, in fact, "funky", then how come that doesn't show up in any way at all except with THIS particular application ? Never mind. I am quite content to do without SMCfancontrol. It's not such a big deal. But I'm certainly surprised that the Developer cannot offer any suggestions as to why it refuses to work on my computer, even though I have sent him Crash and Log reports.

TERMINALMAN Note that this is advertised as "officially supporting" Intel-based laptops only. The iMac seems not yet officially supported, which could account for your difficulties. There were a number of different Intel iMac versions released (three as of May 2009, I believe) and Apple likely changed the fan control interface with each version just as they seem to have done with the new laptop versions. It is likely that the author does not have access to all of the Intel iMac variations, so complaining IN CAPS that it does not work for you is a bit over the top IMO. Particularly for freeware/donationware. This is a useful app, works perfectly on three (different) Intel Mac laptops in my family, and will hopefully soon support all the different "respins" of the Intel iMac. Honestly, software is not so trivial to write when the interfaces you're using "evolves" over time. Been there, done that, got the grey hair to prove it.

AVIDMCUSER @NOTAFOOL - After attempting to launch the application, did you look in your menu bar? I know you are not a fool but it 'is' the only indication after launch that in fact it has launched and the settings can be configured through the menu bar only as far as I know. The preference window is then launched where you can configure it. --just in case you missed it.

YEMENI This app is great! All my high temperatures went down except for the Power Supply (after I installed two additional hard drives in the optical bay). I am now using a usb fan through the optical drive tray opening to to cool it down, but damn it's noisy. Please fix the Power Supply fan control bug and I will be forever grateful.. or show me exactly where to modify the code to fix it. | |
